Notes concerning controller diagnosis
KTS modules are either powered via the power sup-
ply that is delivered or through the OBD interface of the
vehicle.
!
In testing steps that require starting the motor, the
battery voltage may drop to a point that the supply is
no longer guaranteed via the vehicle. In these cases,
it may be required to supply the KTS module with the
power supply.
i
On some vehicles, the power supply through the
OBD interface may only be fed after switching the
ignition on.
The connection to the diagnosis interface in the vehicle
is made via
R
the OBD diagnostics cable (Fig. 3, item 3) or
R
the OBD diagnostics cable and the UNI connecting
cable (Fig. 3, item 2) or
R
the OBD diagnostics cable and a vehicle-specific
adapter line (special accessories).
!
The connection to the diagnosis interface in the ve-
hicle takes place via the OBD-diagnosis cable (Fig. 3,
Pos. 3) or additionally via the UNI-connection cable
(Fig. 3, Pos. 2) and vehicle-specific adapter cables
(special accessories).

Notes on control unit diagnosis can be found in the
Online Help for the diagnosis software.

Notes concerning the multimeter and
oscilloscope
Danger from high voltage!
If measurements are taken without a
ground lead, potentially deadly voltages can
be generated.
¶
If no diagnosis cable is connected, a ground
connection is to be made from the KTS mod-
ules before making any V-, R- or I-measure-
ments (Fig. 1, Item 2) made connection
to vehicle ground with the ground cable
provided.
¶
Connect the ground cable as close as pos-
sible to the measurement object.
¶
Use KTS modules only on the vehicle and
not
for measuring voltages > 60 VDC, 30
VAC or 42 VACpeak! Do not perform any
measurements on ignition systems.
¶
Only use the accompanying measuring
cables with touch protection.
¶
Always insert measuring cables in the
KTS modules first and then into the vehicle.
¶
Do not route unshielded measuring cables
close to high-power sources of interference,
such as e.g. ignition cables.
!
To prevent KTS 570 failure, before calling menu point
"
Oscilloscope
", measurement input CH1(–) must
be connected with vehicle ground. In menu point
"
Oscilloscope
", measuring input CH1(–) and measur-
ing input ground are connected internally (floating
measurement, see chap. 7.4).
3.7.4
Firmware update
After an update of ESI[tronic] or ESI[tronic] 2.0, the
firmware of the KTS modules is updated automatically
when the controller diagnosis is started.
To update the firmware, supply the KTS module us-
ing the supplied power supply and connect to the PC/
Laptop using the USB connection cable. During the
firmware update, the USB connection is not to be inter-
rupted. The firmware update can also be done using
DDC (Diagnostic Device Configuration) (see Online help
DDC).
!
The firmware update must always be done using the
USB connection cable (not via Bluetooth) with the
KTS 540 / 570.
